$PECIFICATION forming part of Letters Patent No. 717,814, dated January 6, 1903.

Application filed September 30, 1902. Serial No. 125,399- (No model.)

To all whom, it may concern: l

Be it known that we, JOHN H. CONKLING and FREDERICK S. CHASE, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Tumbling-Barrels; and we do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a sectional side View of a tumbling-barrel constructed in accordance with our invention with the cover detached.

This invention relates to. an improvement in tumbling-barrels-that is, a device of barrel-like character in which coils of wire are p'lacedsaid barrel being mounted on trunnions and revolved, whereby the coils slide back and forth and by rubbing against each other and the sides of the barrel remove the scale or dirt after annealing. Thecoils of wire differ in diameter-that is, the larger the wire the greater the diameter of the coils and in cleaning wire it is desirable that the diameter of the barrel should correspond to the diameter of the coils to be cleaned It is also impracticable to clean coils of various sizes at the same time. Consequently it has been necessary to have a number of barrels or to clean one lot of one size and then a lot of another size. To overcome the necessity of having a number of barrels, barrels or cylinders have been placed within the main barrel, so as to diminish the diameter and adapt the barrel for cleaning small coils; but the introduction of such a cylinder into the barrel did not permit'the cleaning of more than one size of coils at a time. The object of this invention is to construct a barrel by which two sizes of coils may be cleaned at the same time; and the invention consists in the construction hereinafter described, and particularly recited in the claims.

As herein shown, the inner barrel A is open at one end and closed at its opposite end and formed at its closed end with a fiangeB and with a central boss or stud C. Extending centrally through the head and mounted therein is a stem D, and surrounding this stem and having a bearing on the stud C is a sleeve E, in the outer end of which a plug F is placed. This plug is held in position by a nut G on the screw-threaded end H of the stem D. Surrounding the barrel A is a shell I, open at one end and provided with an inwardly-extending flange Jat its opposite end,

which flange closely fits around the barrel A and rests upon the flange B, to which it is secured by bolts K or other suitable means, forming a chamber L around the barrel. On

opposite sides of the shell are trunnions M, 1

H of the stem D, so that as the cover is turned on the stem it will be drawn down into close engagement with the outer end of the barrel and shell. I

WVith a double tumbling-barrel the barrel A and chamber L are about half filled with coils of wire, the larger coils being placed in the chamber L around the barrel A and the smaller coils in the barrel A around the sleeve E, and more or less Water or other suitable liquid is also placed in the barrel and chamber. The cover is then secured in place and the barrel revolved. As the barrel and cylinder are only half filled and as the coils are not bound tightly together, the revolution of the barrel will cause the coils to slide back and forth, and by rubbing against each other and against the sides of the barrel and shell the scale or dirt on the coils will be pounded or threshed off. It will be readily seen that as both chambers may be used two sizes of wire may be cleaned at the same time or either one may be used independently of the other.

Having fully described our invention, What we claim as new, and desire to secure by Letters Patent, is-

1. A tumbling-barrel a centrally-arranged stem consisting of a barrel, a shell surrounding said barrel and forming a chamber between it and the barrel, a cover for said shell and barrel, and means for imparting revolution to the shell and barrel, substantially as described.

2. A tumbling-barrel consisting of a barrel open at one end and provided with a flange atits opposite end, a centrally-arranged stem, a shell surrounding said barrel open at one end and formed with a flange at its opposite end adapted to closely fit about said barrel and be connected with the flange thereof and so as to form a chamber between the shell and barrel, trunnions secured to opposite sides of said shell, a cover to close the open end of the barrel and shell, and means for imparting revolution thereto, substantially as described.

In testimony whereof We have signed this specification in the presence of two subscribing witnesses.
